Question

所以...我出于某种原因决定完全去socket.io服务器端处理，而不是路由帖。但是我遇到了一个函数只能工作一次的问题。第二次，一切都很好，除了数据库没有更新。（背景中可能还有其他问题，但我似乎无法找到它）......哦！并且客户端值仅发出总是发出1，并且不会得到2,3,4等等。

客户端发出：

  $('#battle-wrapper').on('click', 'button#battlebutton', function (event) {
    event.preventDefault();
    socket.emit('fight mob', $('#mobs').val());
    console.log($('#mobs').val());
  });

Socket.io代码：

socket.on('fight mob', function () {
var session = socket.handshake.session;

// Player Variables
var userMhp = session.userdata.tough;
var userHp = 10;
var userDmg = session.userdata.str;
var userDef = session.userdata.tough;

//  Mob Variables
var mobid = 1;
var mobMhp = Math.floor(mobid * 50);
var mobHp = 100;
var mobDmg = 5;
var mobDef = 5;

// Statistic variables
var dmgdeltmob = 0;
var dmgdeltuser = 0;
var rounds = 0;

// Strings
// var userVictory = '';
// var mobVictory = '';
// var userDefeat = '';
// var mobDefeat = '';

// Turn Variables
var userTurn = true;

//start battle loop
while (userHp > 0 && mobHp > 0) {

  // Start BATTLE
  if (userTurn === true) {
    dmgdeltmob = userDmg;

    // mobHp = mobHp - dmgdeltmob;
    rounds += 1;
    userTurn = false;
  } else if (userTurn === false) {
    dmgdeltuser =  mobDmg;
    userHp = userHp - 10;
    rounds += 1;
    userTurn = true;
  }
}

// Start end of battle Calculations
if (userHp <= 0) { // Defeat
  console.log('Lost');
  let sql = 'UPDATE users SET ? WHERE id = ?';
  let post = {
    silver: session.userdata.silver + 1,
  };
  db.query(sql, [post, session.userdata.id], function (err) {
    console.log('1 Silver Success');
    var data = post.silver;
    socket.emit('mob test', data);
    return;
  });

} else {
  console.log('Won');
}

});

我找到了答案，也许不是最好的解决方案，实际上它可能不是。但这就是我所做的，我创建了一个调用登录的会话处理函数，并在刷新时：

 function sessionHandler() {
    // Adding the logged in user to session
    var userId = session.passport.user;
    var sql = 'SELECT * FROM users WHERE id = ?';
    var query = db.query(sql, userId, function (err, rows) {
      session.userdata = rows[0];
      session.save();
      var dataObj = session.userdata;
      socket.emit('start up', dataObj);
      usersConnected++;
      io.emit('users online', usersConnected);
      console.log(usersConnected);
    });
  }

这是处理登录/刷新的基本逻辑。遗憾的是，我似乎需要将所有逻辑添加到函数本身中。因为一切都在函数外部返回undefined，但在同一个块内。

// User logs in
  if (session.passport === undefined) {
    socket.emit('not logged', destination);
  } else {
    if (session.userdata === undefined) {
      sessionHandler();

      // console.log(session.userdata.username + ' logged in');
    } else {
      if (session.userdata) {
        delete session.userdata;
        session.save();
        sessionHandler();
      }

      // console.log(session.userdata.username + ' refreshed their session');
    }
  }

Socket.io函数只工作一次，然后停止
